Introduction and Purpose: The purpose of this study is to study the EndoActivator, SonicLine and Eddy systems used for sonic activation in root channel irrigation, calcium hydroxide and debris cleaning effects from irregularities in root channels. Method and Requirements: 110 solid upper middle cutting tooth crone part is removed and root channel extension processes are done with ProTaper Universal. The roots were vertically divided into two and a piece of artificial rubber was prepared on the canal wall and 55 amounts of debris and 55 amounts of calcium hydroxide were applied. The combined halves are hermetically covered, then irrigation procedures are applied. In the trial groups (n=15) the total sonic activation time was determined to 60 s; 30 seconds of this was applied in the presence of NaOCl in the channel, 30 seconds in the presence of EDTA. After irrigation, the amount of debris and calcium hydroxide remaining in the shell is subject to a standard score by x40 extension from the samples that are dry and reopened. The scores were tested by Kruskal-Wallis and Dunn-Bonferroni (p<0.05). STATISTICAL RESULTATES: In the statistical review, there was no significant difference between the sonic activation groups and the control group in terms of calcium hydroxide cleaning effectiveness (p>0.05). The sonic activation groups remove debris more effectively than the conventional spray irrigation group (p<0. It has been observed that the sonic activation system groups have no significant differences (p>0.05) between each other. CONTRIBUTION AND RESULT: The new systems, Eddy and SonicLine, can be said to give an equivalent result to EndoActivator in terms of debris and calcium hydroxide elimination. New studies on the mechanical characteristics and clinical applications of these systems can be considered.
